The CLP has begun "trimming the fat" in the public service, dismissing the CEOs of the environment, lands, resources and business departments as well as Public Employment Commissioner Graham Symons and Under-Treasurer Jennifer Prince.

Former Health Minister and current Member for Casuarina Kon Vatskalis said the Labor Party relied on the knowledge these officials held while his party was in Government.

"When we came to government after 21 years of the CLP government, we did not sack people," he told 105.7 Breakfast.

"We rely on their knowledge - it's going to take out of the system so much competent knowledge."

He said those fired would not be easily replaced.

CLP Member for Goyder, Kezia Purick, said she could not comment on the Chief Minister's decision to axe the jobs before Terry Mills had made the announcement publicly.

The former deputy leader of the Opposition has also faced disappointment in wake of the CLP's rise to power, with her expected position of Deputy Chief Minister going to Member for Araluen Robyn Lambley.

As the Government divided portfolios yesterday, Ms Purick was offered none, while the Chief Minister delegated ten to himself.

Ms Purick was offered the position of Speaker, which she says she will discuss further with the Chief Minister.

"Course I was disappointed but that's the way it goes in politics," Ms Purick told 105.7 Breakfast.

The moves have sparked speculation Ms Purick was considered a threat to Mr Mills leadership because of her support for CLP Member Dave Tollner.

When asked if she had offended the Chief Minister in some way, she said "you would have to ask the Chief Minister".

She said the regional portfolios, such as resources, which she had hoped to hold may have gone to Willem Westra Van Holthe because of his electorate in the Katherine region, where resources will play a strong role over the next term
